https://youtu.be/yH3JdGb0znc This is one start in an ongoing project. That the applicable physics of the event is presented accurately. There are repeated misconceptions about the physics of the event that are repeated over and over either out of ignorance or for personal gain. Even in the allotted ...

Physics of The Bottom Arm in the Immediate Post Take Off The immediate post take off is regulated by the dispersion (not loss) of initial kinetic energy into 3 areas. 1) residual kinetic energy (horizontal veloocity) 2) pole energy and 3) potential energy. The lead arm can play a role in the directi...

GV analyze this problem. We have two identical masses moving at the same speed perpendicular to a gravity field on a frictionless surface and in a vacuum (so that we can ignore friction losses). At the same time the both encounter horizontal planes one at 5 degrees and one at 30 degrees. Describe th...

Kirk, My model for this is again Lazero Borges. OP see the "Swing in Slow Motion" video on youtube. https://www.youtube.com/watch?v=7v6L4p0bNaE Excellent continuous motion. Notice that with Borges as with Bubka and Lavillenie that the angle of the hips tilts down towards the runway.

From a purely physics perspective we can form an analysis of the event that takes the pole out of the analysis and simply resolves its forces into x and y forces. Once one takes this perspective then what is left is the energy relation of the CoM path where its horizontal or x velocity is relative t...

This may help. http://www.polevaultfactory.com/PoleVaultFactory/Switch_Point.html I call the distance from take off to switch point the "transit". When you move the grip up you also change the pole take off angle, lowering it, and the transit distance, lengthening it. Now, if you have basi...

Japanese pole vaulting robot. In preparation they apply differential equation analysis of pole bend and where... "We focused on the advantage of input bending moment. To compare that we conducted follow experiment. First, we experimentally compared the original buckling model treating C as cons...

Philosophy of Argument In that the nature of this argument is at best ill defined and subject to the whims of whoever is posting, I'm going to try and define it once again. This will not be much about coaching or physics, but the nature of the discussion at hand. In Defense of the Petrov Method I sh...

The problem is that you think there needs to be a "scientific" response to your practical observations. That's not how "science" works, or, you're working backwards. In this, the property of pendulums is proven science which YOUR observation goes against. OR, again, the point of...
